Default rule for combining multiple descriptors in one macro screen
There is a default processing rule that applies when multiple descriptors are combined in one macro screen. It is called the default combining rule and it operates as follows:
- Evaluate all the required descriptors (that is, descriptors for
which the Optional field is set to false).
- If all are true, then the screen matches.
- Otherwise, go to step 2.
- Start evaluating the optional descriptors (descriptors for which
the Optional field is set to true).
- If any optional descriptor is true, then the screen matches.
- Otherwise, go to step 3.
- If you reach here, then the macro screen does not match the application screen.
